Current app build has a couple of issues, the main one being the app not opening on first attempt. Seems to get stuck at the loading screen and only opens if you close it and open again. Another very frustrating thing with the app is the screen constantly jumping back to the top or the bottom when you're trying to make a payment. Screen won't stay fixed where drag it to. Like a want to see the balances of accounts while I'm typing in the payment amount but it won't let me. This used to work

whenever I try to log in the app crashes. I've cleared cache and reinstalled it and it doesn't work. I rely on the app to quickly check my balance but if it doesn't get fixed soon I'll have to switch banks that has a more reliable app.

Easily the worst banking app I've ever used. I have maybe a 20% success rate of signing in - either it buffers endlessly or I get 'failed to authenticate' over and over. Different pages of the app take ages to load and the design is unintuitive and feels 10 years old (probably because it is, I don't think the UI has changed since I opened my account). I've wanted to switch banks forever solely because of how bad this app is and would have done it by now if switching wasn't such a pain.
